Description

The present invention relates to skin compositions.

In recent years, coenzyme Q10 has been attracting attention as a component having remarkably excellent moisturizing ability among various functional ingredients exhibiting a moisturizing effect. However, while coenzyme Q10 can exert a remarkably excellent moisturizing effect, it has the disadvantage that when it is attempted to be incorporated in a formulation in a high amount, precipitation and the like tend to occur, resulting in deterioration in formulation stability.

Therefore, attempts have been made to impart stability to various formulations containing coenzyme Q10. Specifically, a water-soluble composition containing a specific amount of coenzyme Q10, a specific amount of two polyglycerin fatty acid esters, and water (see, for example, Patent Document 1), coenzyme Q10, a water-soluble physiologically active substance, and a specific an emulsified cosmetic containing an oil agent (see, for example, Patent Document 2); 3), a water-soluble product containing coenzyme Q10, a hydrophilic polyglycerol fatty acid ester, a lipophilic sucrose fatty acid ester, and an aqueous phase component (see, for example, Patent Document 4), coenzyme Q10, phospholipids, and polyglycerin Emulsion compositions containing fatty acid esters and polyhydric alcohols (see, for example, Patent Document 5) have been proposed.

However, although these attempts can provide formulation stability, they only solve the instability of formulations in specific dosage forms, and skin care agents in various dosage forms such as liquid, gel, milky lotion, and cream. It is not a technology that can be diverted or applied to In addition, many of these attempts are techniques aimed at imparting stability to formulations, and are not fully satisfactory in terms of feeling after application, such as lack of stickiness and moistness.

In Evaluation Tests 1 and 2 below, a liquid dosage form was employed in order to make it possible to more clearly determine the presence or absence of precipitation due to coenzyme Q10 of component A.

(Sample preparation 1)
According to the compositions shown in Tables 1 and 2, skin compositions of Examples 1 to 7 and Comparative Examples 1 to 5 were prepared in a conventional manner and subjected to the following evaluations. The results are shown in Tables 1 and 2 together. In addition, all compounding amounts in the table are values converted into pure components.

(Test Example 1: Evaluation of formulation stability)
Each sample of Examples and Comparative Examples was sealed in a 50 mL transparent glass container and stored in a constant temperature bath at 0° C. for 4 weeks. After that, the appearance was visually observed and evaluated according to the following evaluation criteria.

<Evaluation criteria for formulation stability>
○ (good): no deposits attributed to coenzyme Q10 are observed Δ (insufficient): slight deposits attributed to coenzyme Q10 are observed × (poor): deposits attributed to coenzyme Q10 is clearly recognized

(Test Example 2: Evaluation after application)
About 1 g of each sample of Examples and Comparative Examples was taken on the palm of the hand and applied to both cheeks so as to be familiar. After 30 minutes from the application, a sensory evaluation was performed on the "stickiness" and "moisture" of the applied portion, and evaluation was made according to the following evaluation criteria. The evaluation was carried out under the condition of 25° C. by 10 professional evaluators, and the evaluation by each evaluator was comprehensively determined. In addition, in Test Example 1, evaluation after application was not performed for the formulation stability evaluation results of "x (poor)".

<Evaluation criteria for stickiness after application>
○ (Good): Feels no stickiness at all and has a good feeling of use △ (Insufficient): Feels slightly sticky and does not have a good feeling of use × (Poor): Feels sticky clearly, Bad usability

<Evaluation criteria for moist feeling (moisturizing effect) after application>
○ (Good): Moisturizing (moisturizing effect) can be felt △ (Insufficient): Moisturizing (moisturizing effect) can be felt slightly, but it cannot be said to be good × (Poor): Moisturizing (moisturizing effect) effect) is not felt at all
